I've done a lot of clear blue plus tests in the last 2 weeks There have been very faint lines appear in the first 2 mins. I went to Er a few nights ago for a severe migraine they tested me there and it came back negative. I just did 2 more and the lines are still coming up faint. Used some internet cheapies and they come up negative I'm so confused! I have irregular periods so no idea when I ovulated :( just don't know what's going on! Friends say these tests must be positive when they saw them but hubby is in denial and says the other line is too faint. Why would the hospital urine test come back negative surely they are most accurate??this is what they all seem to look like
